实操小贴士
- 为提升“可读性强的标题留白”，在提示词中明确“large clean negative space for headline / wide empty area for text placement / top band of clear sky / side wall clean surface”，并始终加入“no text, no logo”避免AI生成伪文字。
- 高对比配色落地：在背景与服装色描述中加入明确的色名与简短色值描述（如“charcoal #2B2B2B and saffron #FFA400”），有助于模型倾向相应色域；若偏色，可通过ControlNet-Reference或后期调色统一。
- 系列统一：固定镜头词、光线风格与材质描述，仅更换场景与留白位置；用相同seed小幅迭代，确保多图连贯。
- 输出后期：在PS/AI中添加标题与副文案；以留白区为版心，文字用高对比无衬线，行距略宽，确保在移动端阅读清晰。
以上三组A/B方向兼顾海报与社媒的视觉需求，突出了“轻盈防风”的产品特性、年轻通勤的场景语境，并为标题留白与高对比配色提供了稳定扩散可执行的明确指令。
